South Korea's cyber alert level at 'infocon 4'

The cyber alert level in South Korea is now at "infocon 4." That's what South Korea's defense minister calls a "general threat."

Business Week reports that the Korean Communications Commission also raised its alert level to "caution." Both alerts are a notch above the standard default for cyber vigilance.

As many as 40 South Korean websites, including at the presidential office, the National Intelligence Service and Ministry of National Defense were targeted by hackers in March. The cyber attacks were believed to be from North Korea.
